BuzzFeed News has updated this post to clarify that it was published in 2014 and is unrelated to the attack at an Ariana Grande concert.

The original post from 2014 follows:

The allegations range from fall-outs with co-stars to ignoring and/or being rude to fans, being controlling on set, and issuing photographers with long lists of demands. Celebrities including The Cab singer Alexander DeLeon and E! News host Giuliana Rancic have also branded her rude.

However, the latest development in this tale is pretty damning. Grande apparently said she hopes her fans "all fucking die".
